Port sediment pollution by maritime activity

点击翻译按钮获取中文摘要

Biomonitoring procedure using some environmental organisms was applied to assess pollution of port sediments collected at high maritime activity. Some sediments were very toxic to marine photobacteria, which could respond according to the quality of the port sediments. It was, however, difficult to ascertain the observed toxicity with residues of some antifouling compounds and polycyclic aromatic hydrocarbons in the toxic sediments. It was suggested that a wide variety of toxic compounds existed in port sediments.
